I was employed by the CCSR as a Research Fellow, which meant a slightly better salary than the student grant. I completed my PhD in the Centre for Communication Systems Research (CCSR), University of Surrey investigating Traffic and congestion control functions for satellite ATM networks with emphasis on guaranteed Quality of Service (QoS). As a result of my research I have more than twenty publications at international conferences including papers published in books.

After a while as post-doc in the university, the recommendation by most friends was that I should move to industry to get some hands-on experience. So, I joined Nortel Networks Broadband Satellite Network Division as Senior Research/Systems Engineer. My main responsibility was to write system requirements for the Astra broadband satellite network and to lead the definition of the systems IP architecture. At the peak of the Telecoms boom Nortel decided to decrease their activity in the satellite area to concentrate more on their terrestrial core business before going bankrupt.

After two interviews in the US I joined Intelsat as Senior Network Engineer to work on the Broadband Satellite programme. When Intelsat changed from an Inter-Governmental-Organization to a commercial I was promoted to Principal Systems/Network Engineer and joined the Telecommunications Service Development group. I then applied and was offered the position as Network Management Systems (NMS) Manager in the Network Engineering and Implementation group. (more)
